It is a matter of concern that there continues to be no single, agreed figure for the aggregate number and the breakdown by nationality of seasonal agricultural workers, given the importance of this data for the formulation of policy. The Government, employers and representative bodies must work together to develop a common methodology for measuring the aggregate number and the breakdown by nationality of seasonal workers in the food supply chain. In order that Defra’s data commands confidence with stakeholders and within Government it should seek to ensure that these statistics are designated as “National Statistics” by the independent Office for Statistics Regulation.
